I think I might be jumping on this band wagon as well. This sounds very interesting to me, and something that might actually be worth while. I do not race my car, or invest in high performance upgrades. My interest in this is that I want to try to "refine", or smooth out the ride, of my car. Does everyone agree that this would do such? The only other problem I may see with this is that I'm not sure if I can personally do this task. I see that it requires tools that I don't have. With this in mind, would it still be worth the cost if I had to pay a mechanic 50 bucks for an hours worth of labor?
